A Rutgers football player quit the team, alleging his defensive coach verbally abused and bullied him in a spring study hall session, leading to unfair treatment during the season.

Defensive back Jevon Tyree and his parents are seeking disciplinary action from the university against defensive coordinator Dave Cohen, NJ.com reports. Tyree has accused Cohen of using profanity and threatening to head-butt him in front of teammates and an academic adviser, who reported the incident. Cohen was reprimanded by the school, and apologized the day after the incident.

The redshirt freshman, on a scholarship, quit the team Nov. 6 after alleging Cohen treated him unfairly as a result of the incident.

The incident comes seven months the controversial firing of the university’s men’s basketball coach Mike Rice for bullying his players, and on the heels of the Miami Dolphins’ Richie Incognito hazing of Jonathan Martin.
